Yes, when MF closed down the assembly line on the 4800 series tractors a man named McConell bought the rights to build it along with some of the parts inventory. He got a contract with MF to supply tractors through MF dealers. He only built about 13 tractors, all 5200's with 425 HP Detroit engines and Alison Automatic transmissions. These were Red, just like the 4800's. Had a hard time selling or working with MF and his contract was finally cancelled. He then renamed his tractor McConell Marc and it was painted yellow. He sold fewer of these and finally quit. I have literature on both colors in my file. He sold potato harvestors out of his store in Grand Forks ND. He came out to my place to try to sell me one of these tractors when he was here once. He put the tractors together in his South Carolina Plant.
